In Beaker A, you have 65 mL of a blue liquid that has a mass of 45 grams. In beaker B you have 65 mL of a yellow liquid that has a mass of 85 grams. Assuming no chemical reaction occurs and the liquids are capable of safely and thoroughly mixing together with one another, what would you expect to happen based on what you learned in this lab? What will the beaker loo like when you pour them together?
